Subject: mm: call vfree instead of __vunmap from delayed_vfree_work
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=5d3d31d6fb17a8eb83af50ea8a0616a3cfde3e58;p=linux.git

mm: call vfree instead of __vunmap from delayed_vfree_work

This adds an extra, never taken, in_interrupt() branch, but will allow to
cut down the maze of vfree helpers.
